I\'m connecting to my Subersion server (VisualSVN server 1.6.3) using Ankh v2.0.5250.202 on VS 2008
The current url for my repository is https://svnserver:8443/svn/f
In the daily builds of AnkhSVN (and since March 2009 the stable version) the Switch command will handle this case for you.
AnkhSVN will detect that the repository root doesn't match and then it will ask you if you wish to relocate.
See http://ankhsvn.net/daily/ for the daily builds.
